I haven't read through the entire thread yet, so this may already have been covered.
First, numbers two and three are reversed. The second thing you do is set saddle setback from the BB. Saddle to bars is the third thing.
Second, the measurement should be to the nose of the saddle, not the center.
To do this, you'll need either a plumb bob or a drywall T-square, and a four-foot level.
Park Tool has a great guide to recording the measurements, then transferring them to another bike.

It's worth all the extra effort, BTW. I had this done at my LBS last October. All four of my bikes were a little off from one another. They're all withing a mm or two now and it's so much nicer when I switch from one to another
